Problems solved by technology

[0004] Existing warning signs are divided into non-electronic model signs and electronic signs. Compared with electronic signs, model signs have fixed slogans and are not easy to change. Secondly, visibility in rainy days is poor. Therefore, more and more electronic signs cards are replacing template cards
[0005] However, the switches of the existing electronic cards are controlled manually in the control room. There is a delay between the opening time of the electronic cards and the time of rain conditions, and there are also warning signs such as "It is raining and the road is slippery, drive carefully" and so on. , causing driver confusion and a waste of power resources, and a waste of human resources for controllers

Abstract

The invention relates to the field of road safety, and discloses a road warning device in rainy days. The road warning device comprises a warning board, a controller and a humidity sensor, wherein an electronic slogan is arranged on the warning board; the humidity sensor is used for transmitting a detected rain signal to the controller; the controller is used for controlling bright and dark conditions of the electronic slogan on the warning board. The warning function of the road warning device can be automatically switched on in the rainy days, and the warning function can be automatically shut off; the road warning device is wide in application range, does not need manual manipulation, and realizes intelligent automatic control.

Description

technical field [0001] The invention relates to the field of road safety, in particular to a rainy road warning device. Background technique [0002] With the development of the automobile industry, more and more vehicles appear on the road, and people pay more and more attention to road safety. A large proportion of investment in public safety is in road safety facilities. In addition to building expressways or elevated roads to disperse traffic, In addition to rational planning of road design to reduce accident-prone road sections, it is more important to set up warning signs on both sides of the road to remind drivers to drive carefully. [0003] Weather is one of the biggest factors affecting traffic. According to statistics, the traffic accident rate in rainy and snowy days is 3-5 times that in sunny conditions. Therefore, especially in rainy and snowy weather, drivers need to be reminded to be careful. Drive, slow down in time to keep the distance between cars. [00...
